invention, the same comprising,essentiallya pair of flat members or legs 12v and 18. respectively.: The inner ends*` of vsaid respective members or legs 12fand 13. are arranged tO-j j gether `in y.mutually overlapping relation.` lntegrally connected with vthe innerjend of the member yor leg 12is a spring or tension washer element 14, which'is Adoubledouu wardly and Aover the outer face of;` thelniem-A bergor Vleg 12, thusforming a loop connec-ytion lwhich slightlyspacesthe outer por? tion of the washer element lflfromvthe body of the member or leg 12, while the opposite free end 16 ofV saidl washerpelementjllt.con-

bers or legs 12 and 13 and throughythe body verges towardand lcontacts-withsaidQOuter Y faceof said member or leg 12. Extending j through saidy overlapping ends of thermen@n 80 of vsaid washer element `1st `is .the shank 17 ofapivoting rivet having at its respective ends exterior heads ,1 8 and '19.. `When.- the rivet is vheaded over,v the washerr element `1 is subjected to a permanent tension whereby it "thrusts, outwardly .upon thehead i 18 to draw upon the opposite head 19and thus force .the meeting surfaces ofthe overlap-i 'ping ends of the members "or legs 12 and 13 into a strong frictional engagement or contact .one with the other. The frictional engagement or Contact thusfestablished atl the connect-ing njoint'between the/members f Y l or-legs12 and 13 permits the same to beadjusted to'various positions in relation one to the other, when `suiiczient force.l is applied thereto to,overcome.such established frictionalresistance, but when the desired ad@A justment isV made the established frictionalr'` bers or` legs against accidental displacement therefrom. `Connected with the free end'j116' cOtsaidV washer elementfilt a transverse n socket clip orjyoke 2O which is opposedto and which cooperates Awith the .faceV of? the' member .or leg 12to 'providea means toreceive'and.y hold, a pencil `21er other mark,-

resistance tendsto efficiently hold the meming elementv when it is vdesired to utilize the tool orinstrument as acompass. In .order Y ,to provide' a -means fordeterminingjthe proper relative posltlons 0f the-members vor instrument asa straight edge or square, the

'following elements areV provided. integrally formed and struck from the inner end of said ymember or leg 13, ata rcornerthereof bveyond the point of its pivotal connection with the member or leg12, isxan upwardlyiturned stop-lug 22 which projects from the mem- Vber or leg 13 toward the opposed-leg or-ineinbei' 12. The, marginal portion of one side of said member or leg 12, 'and also if .de-

sired,4 the adjacentl overlying edge of theV washer element 14, is cutaway to provide aV receiving notch 23 in which said stop-lug 22 is received and seated when the membersA or legsV 12'and 13 are turned to longitudi nally aliiied relation'one to the otherto thusV providea straight edge, as yshownin Figure 1r of the drawings. vThe outer corners of the yinner extremity ofthe member or vleg 12 where joinedby the washer elementy 14 are.

cut away, as atf24,to thusperinitsuchparts to clear the, stop-lug 22 ,when the members are turnedtoadjust the saine in angularrelaytion yone to the other. 'The marginal por- 'tion of the opposite side of said member or lega12, and also if desired, the adjacent overlying edgeot the washereleinent 14, is liliewisejcut away V,to provide aV second receiving notch ,25 in which said stop lug 22 is received V'and seated whenthe members or legs 12 and :13 are turned to adjust the same at right Vangles one'to the other to Athus provide a square, as shownin Figure?? of the drawings. Projecting ylongitudinally Voutward from the outer free extremity of the' member or leg 12, and -in alinenientlwith one longitudinal edgethereof, is a sharpened spur for point 'g 26, and, indike manner -the freeextremity ofgthe'iiiember or yleg 13is also provided with a similar sharpened spur or point 27. As shown in YFigure 2 vthe members or'legs 12 and 13 .maybe adjusted at various angles divergent from the intermediate pivotal connection, so that the tool or'iiistrument may be used asV dividers, the sharpened spurs or points V26V and 27 constituting the 'free terminals ofthe members oilegs when |the tool i or instrument is vsoeniployed.

lReferring now to Figure 4 of the drawings, the tool or instrument is shown with a pencil 21 opera-tively engaged :by the yoke or clip 20 to attach the saine to the member y or leg 12, so that the pencil may be employed in conjunction'with I.the 'other vmember or nlegl to convert thetool or instrument for use asa marking compass, aswillbe understqod. v .Y

4Referring now, more l especially,'to Figures 6 tov9 inclusive, thei'eis shown therein* vaksonieivhat modilied arrangement'and con- 'struction of friction joint o r pivotal con- Ynection for the members or'legs ofv tlievtool or `instruii'ient.` In these views, the reference character 28 indicates one member or leg and29 lthe' other member or leg. The inner ends of' said respective vmembers or legs 28 and 29 are arranged Vtf'igetlier in 4mutually p. i.

overlapping relation.y The extremity of thev inner -end ofthe member or leg 28is turned outwardlyV for the greater portion of its ex'- port 30. Thereinaining portion of said eX- l ftreinity'is turned.downwardly orA inwardly `toward the other member or legv 29 to pro-1 vide a stop-lug 81,-which cooperates vwithr" either the notch 52"at Aone side margin ot the member or leg 29 to determine thel rela- A tive positions of both members Qr-legs28 and 29 when disposed to arrange fthe tool or vinstrument as a .straight edge, or withthe notch 33 at the opposite side -margin of the niemberor lleg 29 to deterinine'the relative )ositions .of 'both members or le0's1f28` l s of said Ytension washer'34 is the shank '.86 of a pivoting -rivet `having at rits respective 1 ends extei'iorrheads 87 and S8; Whenthei 10ok -e rivetis headed over', the washer lelement 34 is subjectedtoa permanent tension, whereby it thrusts outwardly upon .the vhead 37 to draw upon the opposite head 88 fand `thus force the meeting surftaces'of the overlap'- ping ends vof the membersvor'legs 28 and V429 into a strong'iri'ctional engagementor conn tact one with the other, which, while permit ting pivotalmovementof the members or legs to eiect desired adjustment thereof, will nevertheless tend toV ,maintain thesame against accidental displacement from the poiio siftions `to which` they have been adjusted. c

-In order t'oprevent rotary displacement oft the tension washer, i. e., turning of the same upon the rivet. independently of the"v member or leg 28, the abutinentior'support 30 is pro- ,wir

vided at'one end with an upward extension i Aor tongue 30, and the tension washer is provided with a notch or seat 34 to receive Ysaid extension or tonO'ue 30. lthusinterlocking the washer to the member orleg again-st independent rotary movement.

Referring now to Figures 10 and 11there isl shown -t-herein, another modification of the tension washer element, together with a modified form and relation otpencil lholding clip or yoke, wliicheinbody, however, the

general? principles ofv this invention.. In

these views, the reference 'char-aeters 39"and 40 respectively 'indicate the members or legs TOV 'tent .to .provide a bearing abutment or sup#r of the tool 'or instrument, ythe inner 'ends of Y which-are mutually overlapping." Thereference character 4l indicates the tail-pie'cefor base` of a pencil clip 'or yokememberf'42.

V'Ihe tail-piece or base 4l 'isplaced upon the n outer face of the member'` or leg 89, andthe same is provided at fits outer end with a lateral outwardly turned stop-rib 43. Arranged to eXtend over said tail-piece or base 4l is a'spring or tension washer element 44, which possesses Idownwardly or inwardly turned ends 45l and 46 which tend to space the body of the washer away from the face of the member or leg. When the parts are ..1 assembled, the inwardly turned end 45 of the l washer is engaged against the stop-rib 43,

thus holding the washer against independent rotary lmovement relative to the base or tail,-

piece of the pencil vclip or yoke. VExtending Y through saidy oveilappingendsof the mem-V bers or legs 39 and. 40 and through the body of the washer 44 is the shank 47 of a pivoting rivet having atpits respectivey ends exterior jlieads 48 and 49. r When the rivet is headed .in over, the washer element 44 is subjected ,to a permanent tension, whereby it thrusts outwardly upon the head 48 to draw upon the opposite head 49 and thus force the meeting surfaces of the overlapping ends of the members39 and 40 into a strong frictional en- @agement or contact one with the other, and ilso forcing the meeting faces of the member or leg 39 and pencil clip or yoke base 4l into a like strong frictional engagement or contact one with the other, all to the end that desired pivotal adjustments of the members or legs 39 and 40 with relation to each other, as well as desired pivotaladjustment of the pencil clip or yoke relative to the members orv legs, may be made, while Vnevertheless tending to'maintain such parts against acci- .dental displacement from the positions to which they may have been adjusted.`V j

From the'above description it will be quite evident that this invention, inv its several enibodiments as above described, provides a yvery simple, cheap and-yet Vefiicient combina tion tool or instrument adapted to serve the several purposes cvas described, and one` which because of its novel structure maybe made of sheet metal stampings with a minimum outlay of time, labo-r and material.
